To all whom it may concern:

Be it known that I, JOHN'S. BAnnEs, a citizen of the United States, residing at Rockford,- in the county of. Winnebago and State of Illinois, have'invented certain new and useful improvements in Gearing, of

' which the following is a specification.

The object this invention is to construct a heavy duty. speed mechanism, a tapping mechanism and. an increased speed mechariism for the .drill spindle, said mechanisms dri on through a shaft located-parallel with the drill spindle, and located in rear of the spindle in order that the operative parts will be in the same vertical plane therebyproducing a'well balanced machine.

. In theaccompan ing drawings, Figured is a side elevationo a drillingmachine"con--.- 1 taining my improvements.

Fig. 2is transverse sectlon of the upper portion of'the frame showing the tapping and increased speed mechanism. Fig. 3 is a face representation of alate acting as a. support for. the lever 'emp oycd to transferthe driving mechanismfrom the increased speed mechanism to'thetapping mechanism. Fig.4 is a ranged column 2, its upper vertical section on dotted line a Fig. 2 Fig. 5 is a vertical section on dottedline b?) Fig. 1.

.To the base 1 is connected a vertically arortion formed with a bearing 3, Within which is located a sleeve 4 in a manner to be reciprocated by a the drill spindle with it.

14, I sections 15 "and '16 andhorizontal s'ection pinion, not shown, engaging the teeth of the Above the bearing 3, is located a bearing 6, which guides a drill spindle? connected to the sleeve 4 in a manner to be re- 'volved independently of the sleeve,- but 17, has the "section 15 connected to the branch 11, and the section 16 connected to the bearing 6. The sect on-'17 is provided with two-bearings18 and 19. The bearing 19 supports a spur gear 20, through which .,the drill spindle 7 passes. This spur gear 20 has a clutch face 21. The bearing 6 supports a spur gear 22 which is provided with a clutch ia'ce 23. To the drillspindle 7 is two clutch faces 25 and 26. A shipping lever 27 has a connection with the clutch section.

A supplemental shaft 23 is supported by the bearing. 18 in the horizontal section 17 and in a ,bearing formed in the branch 11. To the lower end of this shaft 28 is connected branches 11 and 12, andis partly inclose'd by the side plates 30,'connecting the branches 1 1 I and 12, A spur pinion 31 is connected to the "shaft 28 so as to rotate therewith; A spur gear 32 hasa splined connection with the shaft 28 in order that it may be moved in -the lengthwise direction of the shaft and at the same time be rotated thereby. Asupport 33- has a connection with the spur gear'32 ina manner to move the spur gear when it is moved. From this sup ort 33 extends an; overhanging arm 34, I spur pinion 35 is supported betweenthe overhanging arm 34 and the support 33 inamanner to rotate idly.

which is pivoted a thumb lever 37.

A plate 33'is adapted to be connected to the sectionlsilii add 16 and is removed from an irregular shaped opening comprising the upper horizonta section 39 and lower section 40 connected by the vertical section 41. The handle 36 extends through this irregular shaped opening and is movable along the different sections thereof. tion of the irregular shaped opening are located two projections 42. Between the projections of a pair the end 43 of the thumb lever 37' may be placed, which will hold the handle from" further movement. The spur upper section 39, the spur gear 32 will be in mesh withthe-spur gear 20. When theliarv die is located in thelower end of the-vertical section 41, the spur gear 32'will. bedropped down out of? mesh with the spur gear 2Q When the handle is at .the right hand end of the lower section 0,'the spur pinion 35 wil be in mesh with t o-spiirjgear 20 and as the pinion is always in. mesh. with the spill gear;

splined a clutch section'24 provided with I a bevel gear 29, which islocated between the Fig. 1 of the drawings to more clearly show the otherphrts. This plate is provided with Beneath each secpinion 35 and spur gear 32 are always mesh. .When the handle 36 is locatedon the From the support 33 extends a handle 36, to Y to T mg in mesh with the spur gear 22, the spur gear Wlll. be constantly rotated. In doing,

eavy work the spur gear 32 and pinion 33 are held disengaged from the spur gear 20. The clutch section 24 is moved down by the shipping leverso'that'its clutch face 26 will engage the clutch face 23, of the spur-gear 22,,

thereby forming a ro'tative connection between the s )ur gear 22 and the drillspindle 7 mesh Wit which is used for light work. the spur gear 32 out of mesh with the spur- ,gear 20 and moving the pinion 35 into mesh withthe spur-gear 20, a rotative connection.

When the c utch face 25 of the clutch section 24 is inengagement with the clutch face 21 of the spur car 20, and the spur gear 32 is in the s ur gear 20, a driving connection is formed between the shaft 28 and the drill spindle 7, but at an increased speed, By dropping is formed between the shaft 28 and drill spindle 7 ,but-in a reverse direction from that imparted to it by the spur gears 31 and 32. ThJS movement is used for tapping.

Aroundthe vertical column 2 is located a bracket 44 and clamped in connection thel'ewith by the lever 45; This bracket is raised and lowered by the screw 46 which is operated by the crank 47. A table 48 is supported by the bracket 44 and is clamped in connection therewith by the lever 49. To the rea'r brace 14 is secured a bracket 50 and from the upper face of-the branch 12 extends a bearing 51. A main driving shaft 52 is sup ported by the bracket 50, the bearing 51 and an intermediate bearing 53. A cone pulley '54 is ada ted to be connected with the main driving s aft 52 through the direct and back caring usuall employe and connections 'eing ormed ymani ul ting the lever 55. A bevel gear 56 is fixed y onnected with'the main'driving shaft and meheswith the bevel ear 29 connected to the haft 28. To the ower end of the rear brace 14 is connected a forked frame composed of the branches 57 and 58, their lower ends connected to the base 1. A counter shaft 59 is'supported in bearings formed inthe branches 57 and 58. A cone pulley 60 and a tight pulley 61 has a driving connection with the counter shaft,

and a ose pulley 62 is loosely supported by the countershaft. A belt 63 forms a driving connection between the two cone pulleys 54 5 having the least side projections, and the arsuitable frame, a vertically arranged drill 13c and 60. y

By this construction of a drilling machine, the drill spindle 7, shaft 28, driving shaft 52 'and counter shaft 59 are all located in the same vertical plane thereby producing a drill ceases rangements of the 'various'sections of. the frame serve to impart strength in the direction of the greatest strain.
